I like the first a lot more.

The story kinda of dragged a lot at the end. They didn't set up the viewers to be invested in the mystery part of the plot so I was only interested in the romance and the characters.

So the show should have ended 1 episode after they got together in my opinion and the killer should have been the father, that way the plot wouldn't be messy. ( too much )

Also I feel like they were trying to create a sense of community/ found family ( I don't know how to explain this well) like in those small town dramas
But I don't think it worked well here as we didn't know the stories of the individuals nor did we need to. So that's another thing that made the drama messy was too many unnecessary characters.
